How do you make your characters go through transformative character arcs that change their flawed core beliefs while still having them feel like themselves by the end? The problem seems to be that my charactersā beliefs are their organizing principle, so once they unlearn them, their whole personality falls apart.Ā
A few things, I think.
1) The first is that I find basing a character arc solely upon "the lie a character believes" to be, ultimately, counterproductive. While it can work, especially in a standalone, I don't think it has much leg room for something bigger (a duology, a series, a long running tv show, etc). This is because the character just learning they were wrong, I think, is often times too clean cut. For the most part, the lies (or fears) that people believe about themselves (for example, a character fears their mental health struggles makes them a burden) is at least partially true. Maybe that character is someone who needs to be carried by their friends -- but isn't a part of love choosing to take on other people's burdens? It's often times much more realistic and much more interesting if the lie is at least partially true. How does the character handle that, and what do they do then? It provides 2 (if not 3) arcs for the price of one, and can be helpful in providing future pathways.
2) Layering. You want to give your characters multiple Big flaws. I'll use my main character from @alvoskia as a short example. She has four main flaws: her tendency for comparison and subsequent resentment; her temper; her penchant for hyper-independence (depending on circumstance), as well as being lying and manipulative. This means even if only one flaw is resolved per book (and even then you can solve parts of them and stretch it out for likely two), I got like 8 books of room and am writing a 6 book series so I can condense and piece things together.
3) Behaviour matters more than beliefs. While the two often go hand-in-hand, with beliefs motivating behaviour, you can ultimately have two characters with the same belief (ie. "I have to be Good to make up for the fact that I'm me") but wildly different behaviour. One character could decide to be good is to put others first always but also resent it and unexpectedly lash out sometimes; another one could put others first and continually devalue themselves to the point they're very easily manipulated and very scared. Same belief, different behaviour. A character's belief can remain and often will, even as they work on changing their behaviour.
4) You can tweak the beliefs. Another solution is that the belief is altered in some ways (alongside the behaviour) even if it doesn't completely go away, which again, is true to life. This means maybe your character is still worried they're not good enough, or still has a fear of abandonment, but the shape of it has changed to "this bad thing may happen sometimes, but I'll be okay Anyway". For a more practical TV example, Zuko from ATLA still believes he must atone for his sins by the end of the TV show, but it's changed from atoning to his abusive father to continuing on a good path of redeeming himself and his nation in having a positive rather than negative impact. The belief and goal hasn't changed, the essence of the character if you will, besides tweaking the Direction and context surrounding it and pushing them through a different channel.
